Title: Improvements in inside box stapler
IPC: B27F7/28
Filed: 1919-12-29
Abstract: 153,485. Craig, E. Dec. 29, 1919. Stapling. - Relates particularly to machines constructed to enter a wire-bound box and drive staples out. wardly through the end walls. The staples are made on a former inside the box, and the former and driver are then moved further into the box to drive the staple. The forming and driving mechanism of ordinary pattern are carried on a slide 5, Fig. 1, which is oscillated by a rod 39 and rotating cam 41. The oscillation causes a suitable length of wire to be fed through a tube 45 from a roller 44 controlled by a fixed pawl 46 on the main frame. A staple is then made by the upward movement of the former 15, 16, Fig. 5, against the wire which is fed through a slot in a movable spring anvil 17. The former and driver are then being moved horizontally by the slide 5 to the driving position close up against the box side 11. The staple is then forced by the driver 7 into the box and the cleat 12, the driver pushing aside the anvil 17, which is mounted on a spring. The former and driver are operated by a bell-crank 51, Fig. 1, controlled by a rod 54 and eccentric 56 on the main shaft 42. The box is supported on a hollow arm 2 of the machine, and the cleat is held at the moment of the driving blow by a movable support 61, which is brought into position by a bell-crank 62 &c. and the same eccentric 56 which operates the driver. When the former and driver are in their lowest position, Fig. 5, they are locked against relative movement by a latch 25 pivoted at 26 to the driver and engaging at 28 with the staple-former. On the upward movement of the driver and former, a cam 30 on the latch 25 engages a cam 31 on the slide 5, and the former is released from the driver and simply pressed up against the box end by a spring 35, while the driver continues upwards to press home the staple. The ends 58, Fig. 11, of the arm 2 are bevelled to enter the corners of the box.

Title: Sorting systems
IPC: B65G47/50
Filed: 1975-08-08
Abstract: 1525591 Photo-electric sorting systems AMERICAN CHAIN & CABLE CO Inc 8 Aug 1975 [9 Aug 1974] 33133/75 Heading G1A Sorting apparatus Fig. 1 comprises: a conveyer 10; diverters 15 spaced in the direction of conveyer travel; means 16 for feeding objects O on to the conveyer 10; object sensing means 13, 14 adjacent the conveyer 10; means 17 providing clockpulses representing increments of conveyer travel; and control means C responsive to the object sensing means 13, 14 and to the clockpulse means 17 to provide an output signal to activate the feed means 16 to introduce a further object on to the conveyer at an instant dependent upon the length of the object passing the object sensing means. When the leading edge of an object arrives at the object sensing means 13, 14, counters 31-33 are gated to accept pulses at half the clock rate from a flip-flop 29, Fig. 3 so that, when the trailing edge of the object passes the sensing means (13, 14), Fig. 1, the count represents the distance through which the centre of the object has advanced beyond the sensing means 13, 14. At this instant the counters 31-33 are switched to accept pulses at the full clock rate so that, when a predetermined count is reached, the counters 31-33 emit a signal indicating that the object centre has passed a point spaced from the sensing means by a predetermined distance equal to the half-length of the longest permissible object. Meanwhile an address reader 19 Fig. 1A has stored coded information carried by the object, which is used to select which of the diverters 15 is to be operated and to select an interval by which the counter signal is delayed so as to trigger the diverter precisely when the object centre arrives adjacent the diverter centre. The counter signal is further used to start the feed means 16, Fig. 1 which has been halted by the appearance of the leading edge of a succeeding object in the beam of a feed sensor 11, 12. To ensure that the selected diverter means 15 has time to operate and return without fouling a succeeding object, the object sensor 13, 14 is located downstream of the feed sensor 11, 12 by a distance equal to vc + ¢ (d - L max ) where # is the conveyer velocity, c is the diverter operating time, d is the diverter length in the direction of travel, and L max  is the length of the longest permissible object.

Abstract: 215,405. Kershaw, A., and Kershaw, r. Dec. 7, 1922. Switches, locking and unlocking; handles.-- Relates to means for preventing the unauthorized starting of motor vehicle engines and comprises a dashboard or like attachment driven through a flexible cable from the magneto and' having a lock provided with a bolt carrying contacts cooperating with contacts in the primary circuit of the magneto. A key inserted in the lock withdraws the bolt so that the primary circuit is relieved from being earthed, the current then passing from the magneto to the make-and-break mechanism, which is carried in the dashboard attachment, and thence to the magneto frame by way of the metal casing of the flexible cable driving the make-and-break mechanism. As shown in Figs. 1 and 2, current passes from the magneto screw 2 to a disc 8 revolving therewith and thence to brushes 7 mounted on a plate 6 in the casing 3 of the magneto. Insulated wires 11 lead the current from the said brushes to a dashboard attachment carrying the make-and-break mechanism (not shown) which is attached to a coupling 14<b> on a disc 14 which is insulatingly mounted on a, shaft 12 driven by a flexible cable 10 from the magneto armature shaft. The disc 14 is engaged by brushes 18 in connection with which are terminals 19, to which the leads 11 are secured, and contacts 23 by means of which the current is diverted from the make-and-break to earth. This earthing circuit is by way of the bolt 20, plate 16, casing 10<b> of the cable 10 to the magneto frame, and is closed' by allowing the bolt 20 to be shot, thus bringing its contacts 21 into engagement with contacts 23. Figs. 4 and 9 show the construction of the bolt 20; it is operated by a lock 24 of the Yale type carrying a lever 24<a> which impinges on a stud 24<b> on the bolt to slide it in its guides 16<a> against the action of a spring 22 tending to close the contacts 21, 23. The bolt is retained in the off " position by means of a hand-operated spring plunger 25 engaging a hole 26 therein, earthing being performed by pulling the plunger and allowing the bolt to be shot. In this position the end of the bolt engages a slot 27<a> in the casing 27 thus preventing it from being unscrewed. Also a detent 28 may engage a recess 29 in the bolt 20 in its locked position, said detent being released by a projection on the part 24<a> of the lock. Figs. 7 and 9 show a modified magneto and dashboard attachment, wherein a plate 30 carries brushes 32 engaging a plate 34 to which leads 11 are secured. The cable 10 is attached to a shaft 37 on which the make-and-break mechanism (not shown) is mounted.
